ETV6/RUNX1 or TEL/AML or t(12;21), or amplification of RUNX1 (iAMP21) rearrangements are recurring abnormalities in B-cell ALL. According to current NCCN B-ALL guidelines, ETV6/RUNX1 or TEL/AML or t(12;21) abnormalities are classified as a good cytogenetic risk factor, and amplification of RUNX1 (iAMP21) is classified as a poor cytogenetic risk factor.
This test can be ordered individually or as part of the B-ALL FISH Panel. See the panel test for more details.
